Visual Simulation of Shallow-Water Waves
T.R. Hagen, J. M. Hjelmervik, K-A. Lie, J.R. Natvig, and M. Ofstad Henriksen
A commodity-type graphics card (GPU) is used to simulate nonlinear water waves
described by a system of balance laws called the shallow-water system. To
solve this hyperbolic system we use explicit high-resolution central-upwind
schemes, which are particularly well suited for exploiting the parallel
processing power of the GPU. In fact, simulations on the GPU are found to run
15--30 times faster than on a CPU. The simulated cases involve dry-bed zones
and non-trivial bottom topographies, which are real challenges to the
robustness and accuracy of the discretization.
